Milling grade GC4330

roughingCVDfor steel

Grades GC4330 and GC4340 are CVD grades optimized for steel milling, offering substantially increased tool life and improved process security. GC4330 is first choice for roughing to semi-finish face milling, while GC4340 is first choice for rough shoulder milling and groove milling. Technical features Inveio® coating for high wear resistance and long tool life New substrate in grade GC4330 with well-controlled grain size distribution, which offers a more reliable and predictable tool behaviour. More consistent tool life with more narrow edge rounding (ER) tolerance. Improved post treatment technology strengthens the insert by modifying its mechanical properties Benefits Increased tool life provides a reduced cost per component Improved process security ensures a predictable performance and less downtime High component quality
